So after loader picks which terminal it likes best, it opens it, uses dup2() to replace its fd (0,1,2) with the new terminal, and then does: setsid(); ioctl(0, TIOCSCTTY, NULL); to switch its controlling terminal to the new terminal (on fd 0). In commit b8886ea3, the code was refactored a bit and the ioctl() got moved *above* the dup2(), which meant that fd 0 was still the *old* terminal, so the ioctl() would have no useful effect. This commit makes ioctl() operate on the correct fd, and changes NULL to '0' (since ioctl takes an int arg, not a pointer). --- loader/serial.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/loader/serial.c b/loader/serial.c index 735ee9e..eeec12f 100644 --- a/loader/serial.c +++ b/loader/serial.c @@ -194,7 +194,7 @@ int init_serial(struct termios *orig_cmode, int *orig_flags, GHashTable *cmdline } setsid(); - if (ioctl(0, TIOCSCTTY, NULL)) + if (ioctl(fd, TIOCSCTTY, 0)) fprintf(stderr, "could not set new controlling tty\n"); if (dup2(fd, 0) == -1) -- 1.7.7.4 _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/anaconda-devel-list
